Subduction-zone megathrust earthquakes, the most powerful earthquakes in the world, can produce tsunamis through a variety of structures that are missed by simple models. These include fault boundary rupture, deformation of overlying plate, splay faults and landslides. In this animation we explore...

Oblique view of a highly generalized animation of a subduction zone where an oceanic plate is subducting beneath a continental plate. This scenario can happen repeatedly on a 100-500 year cycle. The process which produces a mega-thrust earthquake would generate a tsunami (not depicted here).

"This simplified animation illustrates both the subduction-zone processes that lead to a """"""""ghost forest"""""""" as well as the evidence that scientists collected to determine that the Pacific Northwest has had many great earthquakes and tsunamis in the past, and will again inthe future. This...

This animation shows that GPS can record the movement of the leading edge of the overlying continental plate in a subduction zone. The plates are locked and the overlying plate is forced back. When friction is overcome and strain is released, the GPS receiver will snap back toward its original...
